Tiny muscles help bats fine-tune flight, stiffen wing skin

Posted: 23 May 2014 11:53 AM PDT

Bats appear to use a network of hair-thin muscles in their wing skin to control the stiffness and shape of their wings as they fly, according to a new study. The finding provides new insight about the aerodynamic fine-tuning of membrane wings, both natural and human-made.

How touch can trigger our emotions

Posted: 21 May 2014 10:35 AM PDT

While touch always involves awareness, it also sometimes involves emotion. Now, scientists describe a system of slowly conducting nerves in the skin that respond to gentle touch. Investigators are beginning to characterize these nerves and to describe the fundamental role they play in our lives as a social species. Their work also suggests that this soft touch wiring may go awry in disorders such as autism.
